Two aquarium fish, black angel (Pterophyllum scalare) and gold gourami (Trichopodus trichopterus) were procured from the ornamental shop, Aquatic Biosystems and reared for breeding purposes. After rearing few weeks abnormal behaviour was observed of both the species and after preliminary checkup few white dots were found on the skin and fin surface and appeared as white spot diseases. The ciliate protozoan parasite, Ichthyophthirius multifiliis was identified as an etiological agent by clinical signs, wet mount preparation and histopathology. All the infected fish were shifted and evenly distributed to the glass aquaria for treatment. Two treatments were assigned viz., T1 : Elevated temperature (30°C) with 1% salt and T2 : A commercial product (API® Super Ick Cure) and a control group (C1). Highest recovery was recorded in angels (68%) and gouramies (75%) in T1.
